When to use css minifier
Minification makes a stylesheet smaller for delivery. This tool uses a CSS parser and optimizer rather than a blind regular expression, which helps preserve quoted strings and valid syntax. Keep a readable source file in your project and use the compressed output as a build artifact. Test the result with the browsers your site supports.
How it works
- Paste valid CSS.
- Minify and compare the input and output sizes.
- Copy or download the stylesheet.
Try this example
/* Card styles */
.card { color: #ffffff; margin: 0px 0px 0px 0px; padding: 16px; }Before you export or rely on the result
Optimization can change formatting and remove comments. This does not check visual layout or automatically add vendor prefixes.
Does this tool upload my input?
No. This tool processes input in your browser. Optional advertisements are separate third-party content and load only when you allow ads. See the privacy notice for hosting logs and advertising details.
Can I use the result without creating an account?
Yes. CSS Minifier is free to use without an account. Review the result against the limits above and the requirements of the app or document where you plan to use it.
